Blizzard trying to implement MOBA style PvP into WoW for 5.2? Maybe? That will be a little crazy and fun if it does happen. A lot of LoL and DotA players will start to come back if they get balancing pretty good next season. What do you guys think?

I've never played dota or LoL, so could anyone explain what kind of gameplay this is?

3 'lanes', you play a character that starts new each time. 'minion' waves go through each lane, you kill them for gold. Various objectives around the map that give buffs/team gold. You are pushing to get to the opponents base and kill it. There are towers to stop you. That is just an extremely brief summary. Here is a link to the league of legends site, there is more in depth stuff there
